【摘要】 提出了一种新的基于平面光子带隙(UC-PBG)结构的微带天线,在基底上开了一个凹槽,天线贴片位于槽的底部,设计天线的工作频率落在光子晶体的禁带之内。通过对该结构进行数值仿真,证实了该设计在抑制表面波,提高增益及效率和改善辐射方向性等方面的有效性。更多还原

【Abstract】 A new structure of patch antenna based on uniplanar compact photonic crystal(UC-PBG) is proposed by introducing a cuboid groove at UC-PBG substrate. The working frequency of antenna designed lies in the band gap of the UC-PBG. The numerical results demonstrate that the structure is efficient in improving the radiation gain, efficiency and radiation directivity by suppressing surface wave loss.更多还原
